y must be greater than on
was to a 18-200140
b. what is the domain of this function? (2 points)
part ii:

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.

Proportions in triangles solve for x

Typically a point in a three dimensional cartesian coordinate system is represented by which of the following answers in the picture !
